To all whom it may concern:

Be it known that I, Jorm Fannnmolc SI- oar's'r, a citizen of the United States of America, residin in the borough of Brooklyn, in the city of ew York, in the county. of Kings, in the State of New York, have invented certain new and useful Im rovements in Processes of Making Hollow andy Articles, whereof the following is a specification. This invention relates to the production of ornamentalcandyarticles resentingfruits,

The object of this invention is to produce Fig. 3 represents on an enlarged scale a sec-' handsome candy articles of comparatively large size from a small quantity of material and m a rapld and edonomical manner.

The invention comprises workin and shaping of pliable candy into sheets; aying of one sheet over another in a-mold; sealing said sheets together by ressure on a line which constitutes an outllne of the article to be produced and expanding said sheets within said marginal seal into contact with the mold by compressed air or other fluid.

The accom anying drawings represent one form of mol ing'ap aratus for carrying out this process, the mo ds thereof being adapted for the. making of hollow candy articles in imitation of or representing lemons.

Figure 1 represents a lan view in open position of amultiplemol apparatus wherem a plurality of articles may be molded simultaneously. Fig. '2 represents a transverse section thereof on line 2-2 of Fig. 1.

tion at right angles with Fig. 2, showing a transverse section of one of -the individual molds in closed position and having a molded article therein. Fig. 4 is designed to illustrate one step of the process? and, shows a transverse section of the lower half of the molding apparatus (being a longitudinal sec tion through an individual mold) and a plastic sheet of candy laid thereon overlapm the, form of a lemon.

comprises a lower plate 10 ping the edge. of said nold. Fig. 5 shows a similar section, the nozzle of the inflating apparatus being in lposition over theplastic sheet aforesaid. ig. 6 showsa similar section and illustrates another step of the process in which a second plastic sheet of candy is laid over the first sheet aforesaid, the ed e of the second sheet lying over said nozz c. Fig. 7 re resents a transverse section through the mol ing apparatus in closed'position and illustrates thecompletion of another step in the recess, in which the blanks to form the pro uct are severed from the sheets aforei said and the ed es of said blanks are comressed into sea ing contact with each other.

ig. .8 represents a similar section of the molding apparatus in closed position and illustrates another step ofthe process in which the blanks aforesaid areexpanded into contact with the "upper and lower faces f. the mold by fluid' pressure. Fig. 9 representsa perspective view of a com lete candy article 1g. 10 re resents a fragment of one of the molds provi ed with a mechanism'for forcing'the two parts of the mold together to effect the pressing or sealing operation. vation of a cam constituting a part of the mold closing mechanism shown in Fig. 10.

The'same reference numbers indicate corres onding parts in all the figures.

y suitable molding aplparatus may .be-

employedfor carrying out t is process. The drawings illustrate a convenient form of apparatus for this purpose. ilhis apparatus ovided with a plurality of concave half mo ds 11, each provided with a raised marginal lip 12, and a top Jnold plate 20 provided with a corres onding number of concave half molds 21, ps0 provided respectively. with marginal i s 22. v rsely of their mold plates an provided .at their outer ends with recesses 13 adapted to form a knob on the imitation lemon to indicate orsuggest the blossom end thereof. The molds are preferably open on their outer ends at the'front edges of the mold" plates,

their lips 12 and 2 curvin outward at saidends and terminating at sald edges, forming tapering mouths 23 for introducing. the nozzles of 'the blowing apparatus. The lower mold plate 10' is mounted on a base plate 30 or other suitable support and rovided on its rear edge with lugs 14 an 15, and on its front with horizontal arms 16 These molds are dis osed trans- Fig. 11 represents a face elenected y means of hinges 26 and 27 with the lugs of the lower plate 10. The upper plate is adapted to close over the lower plate 10 in suchmanner that the 1i s 22 of the molds 21 come over the lips 12 0 the molds 11 leaving a space between kthem as shown in Figs. 3, 7 and8. Each of the half molds,

. ,adapted to engage a lug the mol as 21 for instance, is provided with a knife blade 28 attached to the outer edge of the lip 22 and adapted to shut over the outer .6 g

e of li 12 when the mold is closed, as shown in ig. 3.

Means are provided for closing the molding apparatus with more or less force.. An suitable means may be employed for this purpose. The means shown in Figs.- 1, 2, 6, and 7 comprise a spring catch 35 secured to the front of the moldplate 20 and provided with a handle 36, said catch being 27 on the mold plate 10, and hold the mold in closed position.

Another form of closing .device'is shown in Figs. 10 and 11, in which a cam lever 38 pivoted to the lower plate 10 engages a stud or projection on the upper plate 20. The swing of the cam lever in one direction, after the top late is swung over the bottom plate, forces t e former toward the latter; and when swung in the other direction said .uppter plate is released. I

eans are lprovided forforcing a fluid between the p astic blanks of candy within to inflate andexpand them into contact with the innerfaces of the mold. Anysuitable apparatus may .be employed for this purpose. The apparatus illustrated comprises a pipe 40 mounted on blocks 41 and 42 which are movable in the guideways 18 and 19 of the arms 16 and 17. This pipe is provided on its rear side with a series of horizontal nozzles 43 disposed opposite the necks or mouths 23 of. the, molds, and onits front face with a handle 44 -b which itis moved toward or. from the mol s. The pipe is closed at one end by a cap 45 or otherwise, and provided with a cook 46 near the other end. A flexible or other supply pipe 50 is connected with the pipe 40 and delivers compressed air, gas, water or other fluid under pressure from a reservoir or other source of supply, not shown, to said pipe 40.

In carrying out this process a candy, which is hard when finished, composed preferably of sugar boiled under a temperature preferably of about 300 Fah., or thereabout, is subjected, while in a warm plastic condition, to a pulling operation in any suitable or ordinar'y manner This working of the candy" produces a gloss thereon. After the pulling operation the candy is formed into a smooth fiat sheet of suitable thickness, say oneeighth inch, more or less; said sheet being preferabl rubbed with buckskin. Then a sheet a 0 said candy in a warm plastic state is laid overthe plate 1O of an open mold, as shown in Fig. 4. Then the pipe 40 is moved inward and the nozzles 43 enter the mouths '23 of the molds and overlie the edge of said cand sheet at said mouths, as shown in Fig. 5. hen a similar candy sheet I) is laid over the sheet won the mold, said sheet I) overlying the nozzles 43 of the inflating a paratus, as shown in Fig. 6. Then the mold 1s closed and the arts of ssiid sheets designed to form the mol ed articles are severed from the remaining portions of said sheets a and b by the knives 28, the edges of such severed portions are com ressed and sealed together by means of thel are forced tight y into contact with the injecting nozzles. Then the cook 46 in pipe 40 is opened and compressed air or other fluid i s 12 and 22, and said sheets under pressure is discharged into the mold between the sheets or blanks a and b andthe latter thereby expanded within their sealed margins into contact with the 'inner faces of the mold. j The mold is com aratively cool, that is its temperature is be ow that of the melting or the softening oint of the candy. The air injected is also l to cool the candy. The candy becomes elow said point 1n temperature and the mold and air both act cooled and hardened sufficiently when the inflation is complete, or soon thereafter, to permit removal. Then the molds are opened, the blown articles taken out, and the operation repeatecL.

This invention provides at small cost ornamental candy articles of large size which can be sold by the piece or by the pound. These the hard candy of which they are composed may have any desired flavoring and coloring.

I claim as my invention The art 'Of makinghollow candy articles which consists in clamping su erposed sheets of hard candy in a warm p astic condition between cool mold sections, injecting a fluid in a cool state under pressure 'into the mold between said sheets while in warm plastic condition, and forcing said sheets by means of said fluid under pressure into contact with '105 articles may be made in various forms and the cool surfaces of the mold, whereby the article is formed and hardened.
